Ah - so @osschar are you suggesting that the 'operation expired' is coming from `xrootd.echo.stfc.ac.uk` as opposed to being able to generated internally by the client? (To be clear, the logs from Raja are from the LHCb physics application). Also @osschar - does that version of the proxy cache unwrap the vector reads into individual read operations? Or does it keep it vectored? -- You are receiving this because you were mentioned.
